Which of the following statements explains why systems naturally progress toward higher entropy? A) Entropy is equivalent to exothermic heat release, and higher entropy results in an exothermic process. B) Higher entropy results in a larger mass of product being produced in a chemical reaction. C) Entropy provides a measure of the disorder of molecular particles, and more dispersed/disordered states are more probable than less dispersed/more ordered states.
